世界上水是一种宝贵资源,任何人无权浪费,有效利用灌溉水是每个使用者的责任。然而,各地水的利用效率是不同的,有些地区水少而珍贵,人们便注意节约用水,相反在丰水地区水的价值低,便有浪费水的现象。影响灌溉效率的因素是灌水技术和费用,水的管理水平,灌溉作物类别以及土壤的性质等。由于这个缘故,在灌溉实践中灌溉效率是被广泛使用的。它是表示一定灌溉方式和性质的指标,可以设计制作评价水的全过程的效率图,用以指示改善薄弱环节,实现更有效的灌溉,是从水源引水直到被作物利用全面对灌溉工作 Water is a precious resource in the world, no one has the right to waste, and effective use of irrigation water is the responsibility of every user. However, the utilization efficiency of water varies from place to place. In some areas, water is scarce and precious. People pay attention to saving water. On the contrary, the value of water in a water-rich area is low and there is a waste of water. Factors affecting irrigation efficiency are irrigation technologies and costs, water management, types of irrigated crops, and soil properties. For this reason, irrigation efficiency is widely used in irrigation practices. It is an indication of the type and nature of irrigation that can be engineered to produce an efficiency map of the entire process of evaluating water to indicate improvements in weakness and more effective irrigation that is directed from the water source until it is fully utilized by the crop
